GARBURETER.

Specification of Letters Patent. Patented N 30, 1915 Application filednovember 3, 1914. Serial No. 870,148.

To all whom it may concern:

Be it known that I, LESTER G. POND, a citizen of the United States,residing=at Seekonk, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement. inCarbureters, of which the following is a specification.

This invention relates to certain new and useful improvements incarbureters, and the primary object thereof is to provide improved meansfor effecting carburization by the employement of a series ofindependent gasolene outlets which present the gasolene to the incomingair, combined with improved valve mechanism which gradually lncreases ordecreases the number of the outlets exposed to the air.

Further, the invention aims to provide improved valve mechanism whichnot only gradually controls the number of outlets exposed to the air,but which also, following movement thereof to a predetermined extentcuts ofl' all of the outlets from the air.

Still further, the invention aims to provide'means whereby the valvemechanism may be adjusted so as to vary the closing of the outlet portsby movement of the mechanism, that is to say to enable the mechanism tobe adjusted so that either a short or a long movement of the same willefl'ect closing of the outlets.

Further, the invention resides in certain details of construction andcombination of parts hereinafter more fully described.

In the drawings Figure 1 is a side elevation of the invention showingsame in position in an automobile. the line 2-2 of Fig. 3. Fig. 3 is afront elevation. Fig. 4 is a section on the line 4-4 of Fig. 2. Fig. 5is a section on the line 5-5 of Fig. 2. Fig. 6 is a detail perspectiveview of a part of the rotary valve mechanism. Fig. 7 is a similar Viewof the other part of the rotary valve mechanism. Fig. 8 is a similarview of the gasolene feed plate having the gasolene channels, and Fig.

9 is a similar view of the top plate which is secured to the plate ofFig. 8, so as to close the upper portions of the channels of the latter.

In proceeding in accordance with the present invention a casing isemployed which Fig. 2 is a section on said chamber, the opening 7 beingcommon and feeding gasolene to a series of transverse channels 8 whichare formed in the upper face of plate 6 and extend through the frontedge of said plate. A plate 9 is superimposed on the plate 7 and has abeveled front edge 10, the plate being adjustable transversely of theplate 6 by means of the screw and slot connections 1l12.' The plate 9acts to close the upper portions of the channels 8 so that the gasolenefrom chamber 4 will, when vaporized, be drawn through the channels 8.

The casing has an extension 13 bored to receive a rotary valve part 14,the other valve part 15 being received within the part 14. The part 14has a longitudinal slot 16 the longitudinal walls of which slot arestraight. The part 15 of the valve has a longitudinal slot 17, the wall18of which slot is inclined so that as the valve is rotated within thepart 14, the wall 18 will gradually expose or cut-off a number of thechannels or outlets 8 to or from contact with the air drawn into thecarbureter through the intake 19 by the engine movements, as shown inFig. 2. As shown in Fig. 5, the inner ends of parts 14 and 15 are openso that the air and the gasolene will pass through said open ends and bemixed together in their passage through.

part 15 and through the pipe 21 which leads to the manifold 22. Theusual throttle valve 23 is located Within pipe 21 and is connected to anarm 25, to which latter a link 24 is pivoted,'the link being pivoted toin working position, the valve parts are adjusted as follows: The valvepart 14 is first moved in such position by the arm 20 as to cause theslot 16 to be fully open to the intake 19'; the valve part 15 is thenrotated by the rod 26 to bring the inclined wall 18 in proper positionfor the slow running of the motor without moving the load, as indicatedin broken lines 18 m Fig. 2; and the arm 25 is then connected to the rod26 to properly locate the throttle valve. After the. adjustment andconnection ofthe parts, as above described, the rod 26 is connected insuch well known manner to .the wheel and foot pedal, that the rotationof the valve 15 may be effected therefrom. The motor is now started andas the valve part 15 has been set to permit-the running of the same atlow speed, the motor will continue to do so until the valve part 15 ischanged to increase the speed. The valve part is now adjusted for normalhigh speed. This adjustment is effected by the rotation of the valvepart 14 by the arm 20, so as to bring one edge of the slot 16 over thepoint of the inclinedslot 17, as shown in Fig. 2.

It will be apparent that depending upon the rotation of the valve part15 more or less gasolene outlets are presented in a straight line to theincoming air and as these outlets are very small a fog-like vapor isproduced by the contact of the air with the gasolene. The structure isextremely simple in adjustment and all parts can be. readily re movedfor the purpose of cleaning.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a carbureter, a fuel chamber, a pair 1 ofadjustable superimposed plates having a series of independent gasoleneoutlets formed therebetween communicating with the chamber, a pair oftelescopic valves having longitudinal slots which communicate with eachof the outlets, one of the valves being formed to completely cut-ofl'the outlets, and means to enable independent operation of the valves.

j 2. In a carbureter, a fuel chamber, a member having a series ofindependent gasolene outlets which latter communicate with the chamber,and a pair of adjustable and independently rotatable valves one of whichgradually exposes or cuts off the incoming air to the. outlets and theother of which is adapted to completely cut off all of the outlets fromthe incoming air or to regulate the amount of air which can come incontact with the entire number of outlets.

3. In a carbureter, a horizontal main fuel chamber having a feed chamber"communieating therewith and arranged at one side thereof and being openat its top, amember on the top of said feed chamber and having a seriesof independent channels on its top face and an opening whichcommunicates with the feed chamber interior and with the channels, aplate adjustable on said member and closing the tops of the channels,and a rotary cylindrical valve arranged at one side of the feed chamberso that the channels are substantially tangential to the valve.

4. In a carbureter, a fuel chamber, cylindrical air regulating means atone side of and spaced from the chamber, and horizontal adjustable meansarranged over the space between the chamber and air regulating means andsubstantially tangential to the last named means to divide the fuel intoa series of separate streams and to cause the latter to communicate withtheair.

5. In a carbureter, a fuel chamber having an outlet, and a pair oftelescopic rotatable valves arranged substantially tangential to saidoutlet and each having a longitudinal slot, one of the valves having astraight edge parallel to the axis thereof and the other valve having astraight edge inclined with respect to the axis thereof.

6. In a carbureter, a fuel chamber having an outlet, and means arrangedubstantially tangential to said outlet to control the outlet having twostraight edges one of which is inclined and the other parallel withrespect to the axis of the means.

7. In a carbureter, a fuel chamber having a straight edged outlet, andmeans arranged substantially tangential to said outlet to control theoutlet having two straight edges one of which is inclined and the otherparallel with respect to the axis of the means, the parallel edge beingadapted to contact with the straight edged outlet to close the latter.

8. In a carbureter, a fuel chamber having an outlet, and a pair ofrelatively adjustable superimposed plates having a series of independentfuel outlets formed therebetween, which outlets communicate with thechamber outlet.

' 9. In a carbureter, a fuel chamber having a fuel outlet, and a pair ofvalves arranged substantially tangential to the outlet and beingindependently adjustable and movable for, controlling the outlet, one ofsaid valves having a slot providing a wall which when engaged with thefuel outlet completely closes the latter. v
